PAsTEUnIzING-MACHINE.

Beit known lthat ive,.EDivARD J.- SPINK and JOSEPH A. Minima, 'citizens of the United States,frcsiding at Council Bluffs, in

A the' county of Pottaivattamie and State: of

Iowa, have invented anew and'useful- Pas- M teurizing-Machine, Aof which. theA following 'is a specitication.

" vOur-invention.relates to improvements in pasteui'izingmachines, and has' for its object tli'eprovision of a simple and eiiicient apparatus by the use' of which liquids may be easily, thoroughly, and rapidly pasteuriaed s o as to-'be rendered healthful'without losing any of their palatable qualities.l

A further object of .the invention is to 'provide an apparatus in whicli-scalding 'of the liquid will be avoided and'in Which-the flow of the liquidwill be automatically. reg- Aulated so "that the entire body will be treated` Without interruption.

A ffurt-her object of Athe invention: is to l provide an apparatus-for the stated purpose which will besimplc in construction, compact in arrangement, and efiicient in opera-- tion.v These stated objects, and such other 0bjects as will hereinafter incidentally appear, are attained in the-use of the mechanism illustrated in the accompanying drawings, and the invention consists in certain 'novel features of the same which will be' hereinafter first fully described and then' -more particularly pointed out in the appended' claims.

In the draivings,-l"ignre 1 is adiamet'rical4 vertical. section of an apparatus embodying our invention. Fig. 2 1s a plan View, partly broken away, of the pasteuriz-- ing disks and 'i he.parts below the same. Fig. 3 is a detail plaiii'iciv of the mechanism whereby the iloiv of' the liquid is regulated. Fig. ltis a. sectional elevation ofV a modification.

ln carrying out our invent-ion,- we employ a 'supportingstructiire consisting of legs 'or standards l and a 'circular band 2 secured.

jecting arms -3 having notched to theupper ends of the said legs, the legs being each provided with inwardly proupper edges,l

as clearly .shown in Fig. -1.

To the'upper ledge of the ring-.or band i 2, we secure a pair of slightly conical disks 4 and 5 which are spaced apart to provide4 a. compartment 6 adapted to contain water,

The supply. of liquid 'or gaseous fuelhavng been'admitted to the supply pipe 36', itwill 4 risc into and fill the burner-and, escaping' fromjtlie same-through the slits-35, will bc"- iguit'ed andwill, consequently, direct a practically Acontinuous -flame "against the under side ofjthelower disk atthe edge of lthe same.' A flue 3 7 is arranged to carryfolf' the products ofcombuston .and has its inner end disposed beneath-the centerofthe pasteurizing disks, and has itsouter end at' 'i any convenient distant. point. to discharge the products tof combustion into the atmosp here.' It will ".be observedfthat this flue extends downward `under'th'e supporting 'band2 seas to avoid the'cuttinr and," con.

'sequently, weakening of the said band and -doe's not 'interfere with"'th e stability of the device in anywa' The ell'ec't of` this flue is vto create a dra tV from Vtherside' of' Vthe apparat-us tow-'afl the center-ofthe' 'sameQsd that the flame issuing .frein-the burnerlwill/ be'caused to follow the iiiden-surface'of; thev lowerl disk so as to heat theentirediskli llieconstruction shown in Figs. l and '2.

In Fig. 4,-we' have illust-rated7tli'e-pasteurfupper disk instead. of being"corrugated,"a hcreinbefore described, [is constructed witlua '.izng disks. as being'4 more pronouncedly .;-;B5

'conical than those Shown-in Figi -1, an'dthe" spiral grooveor tlfough 38 which' leads from i theupper portion'or apex of the disk down to a, discharge spout 439. This construction will operate in' all respectsthe same' as fthe construction preferred, by us' but is' better adapted to operating on a small scalej The operation of our device is believedto. be obvious from the foregoing description, taken in connection with'the'accompauying drawings, The liquid to be treated, as bcfore'stated, is. placed in the hopper 27, thc

compartments 6, the feeding pipeflS, and the pipes 141: and l'liaving been first filled with water; and the plug 21V-inserted in place. The burner being lighted, 'the'liquid in the compartment will be heated" so' that the temperature of the upper pat'eurizingdisk 5 will be .raised but will befmodificdfby the presence of the liquid. in thefompartment between the two disks so that it'c'annot reach such a high temperature as will .be liable t'o scald or boil the liquid to be pasteurizcd;

The' milk or other .liquid will .then llow throughfthe distributing tank 23 onto the pasteurizing disk and will run over-the same through the corrugations therein into the trough 9' and escape therefrom through 'the spout '10. The flowof'the liquid over 'the'disk will be slow enough tol permit all germs thereinto be destroyed, while it will be rapid -e'no'nghto prevent deterioration 1n its quality through scald-ing or boiling.'

Our apparatus' is so 'constructed as 'to .oef`

efficiency in operatiom The'several parus 'cupy `very' little space compared with its;

'easily separated 'so as to be cleaned, ,as-the hopper 27 with the nozzle 26 can b'e lifted olf thepan or'rest 22"and,'by merely re-v moving the coupling 40 from-the feed' pipe- 18, the distributin ftankV 23'may be lifted Y understood.' -The distributing -tank 23 is. provided with a central sleeve 41 adapted to ft around the water feeding pipe 18, and the bottomof the'tank rests upon 'en 'annular shoulderor rib 42 on the .said pipe sothatfit is not-neeessaryto secure thegtankto the pipe'fin orderto prevent dropping'of the same onto the pasteurizing- -disk.V The conf struction of the upper disk, over which the 1 0-*Huid nous, provides .aslarge Ysurface' over which it will spreadl 4so that the -proper jamount othfeatto accomplish thedesired purpose may be absorbed bythe milkivithout destroying. the natural condition -of the same for crcanrorbutter 'making purposes or` altering its. taste. The annular 'supporting band 2 incloses Ythe burper and the 'Water pipes so asvto prevent the'heat. from the -burner passing around the-outer edge of 2O the disksand `thereb)7 reaching the milk,

and atthe-same time prevents the odors of the' burningl fuel impregnatingthe milk;

Furthernwre, this arrangementh'oldsthe heatfbeloui the disk so that the temperature. of the liquid inthe several pipes and the compartiment. between. the two 'disks willVV be kept even While the apparatus-isin use, -and the Varrangement of the .cones isxsuch.

that the proper heat will-be economicallyl maintained. A- larger volume of waterl will absorb and consume a greateramount of hcatto produce the same results'A and thcre by increase .the cost of operation,- wlnle a .f smaller volumeof water 1s apt topermit the sudden generation of steam .which would drive. out the water andproduce a fluctuating temperature. .The flaiue,being created near the outer edge of the disks and thenv being drawn toward 'the center, .pro-

40 duces'yperfect combustion and allows the" fullest extraction-of heatA units to perform the desired work. vInasmuch as. the foul gases and other products of combustion 'are 4carried oli' from the center oi the'apparatus b and below the salue, it is not-necessary to mutilate the disksto provide an exitfor the said gases'and other products and, con-A sequently, theentire surface of the upper disk 'maybe used for the pasteur-ization. Thedisks may be pressed from a single sheet' 'of nietalleavingr no sealns 'or corners there'- in4 so ythat' the surfaces will be smooth and 'easilycleaned, while at the saine time there4 I so andthen' permit the liquid to ow-'ovr-the" .the apparatus which we nowj -nniylic'made when desiredlas are withinthe;
